Purpose: Hemorrhagic shock is the leading cause of death in trauma patients worldwide. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique used to improve the hemodynamic stability of patients with traumatic shock and to temporarily control arterial hemorrhage. However, further research is required to determine whether REBOA with cardiopulmonary resuscitation (CPR) in near-arrest or arrest trauma patients can help resuscitation. We analyzed trauma patients who underwent REBOA according to their CPR status and evaluated the effects of REBOA in arrest situations. Methods: This study was a retrospective single-regional trauma center study conducted at a tertiary medical institution from February 2017 to November 2019. We evaluated the mortality of severely injured patients who underwent REBOA and analyzed the factors that influenced the outcome. Patients were divided into CPR and non-CPR groups. Results: We reviewed 1,596 trauma patients with shock, of whom 23 patients underwent REBOA (1.4%). Two patients were excluded due to failure and a repeated attempt of REBOA. The Glasgow Coma Scale score was lower in the CPR group than in the non-CPR group (p=0.009). Blood pressure readings at the emergency room were lower in the CPR group than in the non-CPR group, including systolic blood pressure (p=0.012), diastolic blood pressure (p=0.002), and mean arterial pressure (p=0.008). In addition, the mortality rate was higher in the CPR group (100%) than in the non-CPR group (50%) (p=0.012). The overall mortality rate was 76.2%. Conclusions: Our study suggests that if REBOA is deemed necessary in a timely manner, it is better to perform REBOA before an arrest occurs. Therefore, appropriate protocols, including pre-hospital REBOA, should be constructed to demonstrate the effectiveness of REBOA in reducing mortality in arrest or impending arrest patients.

This study aims to develop rural house maintenance technique by researching and analyzing the demand for rural house by urban retirees or urbanites who are planning to retire. The target for the survey consisted of urban retirees or urbanites who are planning to retire at the ages between 40 and 65, and were divided into group A, the attendants in rural-related education, and group B, the non-attendants in rural-related education. The contents of the survey included the plan and purpose for rural settlement, the utilization form or residential form of rural house and its expected size, necessary in-house facilities, necessary community facilities, improvement and maintenance factors of rural house, political and legal support for the application of rural house maintenance, etc. The results findings of this study are as follows; 1)For both group, the major purpose of rural settlement appeared to be 'for rural life', utilization form of rural house to be 'acquired ownership or use of empty house', residential form to be 'cohabitation', expected size to be 'under $20{\sim}30$ pung', and expenditure to be 'under $50{\sim}100\;million$'. 2)Most wanted necessary in-house facilities included backyard, multipurpose storage room for group A, and backyard, garden for group B. Necessary community facilities included boardwalk, sewage disposal unit for group A, and boardwalk, shop for group B. 3)Improvement factor for rural house showed 'poor insulation' as first factor for both groups, and for maintenance factor, 'backyard', 'under-floor heating' for group A, and 'environmental-friendly materials', 'backyard' for group B. 4)Most wanted overall political and legal support included 'support on land and real estate supply' for group A, and 'medical and transportation service' for group B. For both group, most wanted support when purchasing a house included 'provision of information on house and realestate purchase', and for legal support, 'legal support for guaranteed house and maintenance' as first factor. The results of this study could be utilized to restructure the rural residence, which would meet the diverse demand of both rural residents and urbanites by providing an opportunity for urbanites to enjoy rural life.

Employment form and gender as stratification factors may generate health disparities in Korea. Previous studies have examined the existence of health disparities by employment form and gender. However, few studies examined how the health disparities can be reduced effectively. This study intends to confirm the existence of health disparities between employment-gender groups and explore the effective health resources which can reduce the possible disparities. Using a national probability sample of Korean adults collected in 2011, we attempts to test the interaction effects between employment-gender groups and health resources on self-rated health. For health resources, 24 variables of five dimensions(social relationship, psychological resource, activity factor, health behavior, and usage of medical service) are taken into account. In results, first, the health levels of the other three employment-gender groups are worse than that of male-regular workers. Second, the effective health resources which can reduce the health disparities are different across the employment-gender groups. An effective health resource for female-nonregular workers is a peaceful relationship with her children. Effective health resources for male-nonregular workers are peaceful relationships with his parents and siblings, low stress, religious activity, and exercise. An effective health resource for female-regular workers is interpersonal trust. These results imply that personal or social interventions for health of specific disadvantaged groups need to focus on specific resources which are more effective for the groups.

Objective : The purpose of the research is to investigate Korean occupational therapists' awareness of Evidence-Based Practice(EBP), basis of clinical decision making, barrier factors of EBP execution. Methods : Form December 2009 to March 2010, 500 questionnaires were sent out to clinical occupational therapists and 160 questionnaire which are returned by the therapists were analyzed through descriptive statistics. Results : There are more female respondents than male. More than 90% of them had less than 5 years experience. Most of respondents hadn't experienced education concerning EBP(76%), and the education is not periodically conducted(55%). Moreover, treatment was being tailored based on subjective judgement. On the other hand, the degree of recognition showed that the professionalism of occupational therapists can be improved through EBP(96%), and be helpful to make clinical decision(88%). Most of the therapists answered that guaranteeing enough time to search the basis of treatment(90%) and participating in the education course(92%) is needed to make EBP applicable. This result shows that while the application rate of EBP is low, the recognition rate of EBP is high, which means it is necessary to revitalize EBP education program. Conclusions : In order to provide quality service, education course and instructor training program is needed. We should also make a great effort to offer evidence-based education to occupational therapy students. Furthermore, EBP has to be carried out to improve the professionalism of occupational therapists, and the research about education program and its effect has to be executed.

Purpose: The aim of this research was to explore nurses' knowledge of and attitudes toward pediatric palliative care (PPC) in Korea. Methods: A descriptive cross-sectional design was used. A total of 196 participants were recruited from the ELNEC-PPC course held in Seoul, Korea. All participants completed a 20-item survey questionnaire which assessed knowledge of and attitudes toward PPC using a 7-point Likert scale. Results: Nurses' knowledge of PPC correlated with their educational level and work experience in the pediatric unit and hospice care unit. The work experience in the pediatric unit, career length in PPC and completion of palliative education course made differences in the attitudes toward PPC. Married nurses scored significantly higher on the parental rights in determining palliative care service for their child, and nurses with master's degree or higher showed a higher level of understanding of and attitudes toward the differences between PPC and adult palliative care. Conclusion: The factors influencing nurses' knowledge of and attitudes toward PPC need be considered to develop a pediatric palliative training program.

The purpose of this study was to examine the trends of length of hospital stay (LOS), which is most likely to be a major attribute to hospital performance. From 1984 to 1994, an average LOS of each hospital was analyzed by factors such as medical departments, bed size, occupancy rate, region and ownership. This study was analyzed changing rate of LOS during 11 years. This rate was calculated by simple regression, which was used only with hospital without missing data during 11 years. This study findings are as follows. 1. The results indicated that the average LOS was steadily increased until 1990 but it was slightly decreased after 1990. 2. This trend could be found in all hospital scale and all group of occupancy rate. Specifically this trends of LOS were found in internal medicine, corporate owned hospitals, and hospitals in major city. But LOS of individual owned hospital was continuously increased until 1994. 3. Means of changing rates of LOS were calculated from 1984 to 1994. If we devided it into two parts, before 1990 and after 1990, most changing rates of LOS before 1990 except individual owned hospital were found positive sign. The changing rates after 1990 were negative sign but small hospital(lesser then 200 bed), individual owned hospital, national & public hospital and hospital in small urban have little change of LOS after 1990. Finally from this results we thought that most hospitals in Korea began to be concerned with LOS. Nevertheless LOS of several hospital such as small hospital or individual owned hospital was increased. And this trend may be caused by a few patients, low occupancy rate, or low profit. This trend of LOS is different from that of other countries. Perhaps this phenomenon is resulted from the reimbursement method. Because of fee for service reimbursement system in Korea the hospitals didn't need to shorten LOS in order to save the cost and increase the profit. Therefore reform of hospital cost reimbursement method will be needed to reduce hospital cost in Korea. We thought that the Korean health authority should consider the reimbursement method by unit of bundle of services, for example DRG and prepayment in the United States. This study presents some limitations such as no insight of severity of disease, case-mix measurement of hospital, and other clinical characteristics that can. possibly affect LOS. However, this study reports an important trend in LOS from 1984 to 1994.

This study aims to figure out the effects of dental hygienists' professionalism and self-efficacy on job satisfaction using structural equations. This research conducted a survey to 616 study subjects. According to the analysis using SPSSWIN 18.0 and AMOS 20, the results are as follows : 1. It was shown that the dental hygienists' professionalism gained 3.34 points, self-efficacy was 3.76 points, and job satisfaction received 3.36 points. 2. It was found that as their age was higher, educational degree was higher, they were married, and working experience was more, their professionalism, self-efficacy, and job satisfaction were higher, which showed statistically significant difference. 3. Regarding the study model, there was positive effect as the correlation coefficient of professionalism and self efficacy was .69, that of professionalism and job satisfaction was .33, that of self-efficacy and job satisfaction was .59. In other words, there was correlation between professionalism and self-efficacy. When self-efficacy was higher than professionalism, job satisfaction also increased. Job satisfaction is affected by various environments within an organization and each individual's internal factors. The reason why job satisfaction is important is that along with the medical service quality and productivity, it is also associated with dental hygienists' individual life quality. In order to cope with this changeful time, it is needed for an organization to make efforts for change to enhance dental hygienists' job satisfaction, and also it is necessary to make endeavors so that dental hygienists can have confidence in their job and their professionalism and self-efficacy can be improved.

This study attempted to examine the relationship between pygmalion leadership and the organizational commitment among hospital employees, and the mediating effect of the leader-member exchange (LMX) on their relationship. For this purpose, we designed structured self-response survey questionnaires, and collected data from 349 employees working at 9 hospitals and ambulatory clinics in Busan area. Frequency analysis, correlation analysis, factor analysis, and reliability analysis were performed using SPSS ver.18.0 program, and the path analysis was performed using AMOS ver.18.0 program. Major findings are as follows. First, some factors of pygmalion leadership were found to directly influence the quality of LMX, while some had both direct and indirect influences on organizational commitment. Second, the quality of LMX was found to partly mediate the relationship between pygmalion leadership and the organizational commitment in hospital organizations. This is the first in kind which was conducted in the hospital setting.
